Back in December we reported on what was thought to be the first battery test that pitted a PS Vita against a 3DS and a PSP. The winner was the PSP, but it cheated by using an extended battery. The big takeaway from the test though, was that the PS Vita battery lasted 46% longer than the 3DS.

Although that test was valid, it just had a game running on a loop with no interaction. That’s understandable as otherwise you’d have to get someone to play each system for several hours. However, one Japanese gamer has now taken the time to do just that and the results paint a very different picture.

Going by the YouTube name kurekureyon, this gamer loaded up F1 2011 on a PS Vita and the 3DS. He then proceeded to play each one while a timer was running until each machine’s battery ran out of juice. The video footage was then posted as a side-by-side comparison on YouTube (watch it below).

This is an impressive test simply because kurekureyon had to play the same game for 9 hours. To make sure the test was fair he also repeatedly played the same F1 track over and over again–something that would get tedious after 10 minutes let alone 9 hours.

We’re glad he took the time and had the patience to do this, though. Unlike the game loop battery test, the 3DS battery lasted much longer than the PS Vita. The Vita managed 4 hours and 4 minutes, while the 3DS continued on to just shy of 5 hours, turning the displays off at the 4 hour 57 minutes mark.

As you can see at the start of the video, kurekureyon took every measure possible to cut power use while he played. That included turning off Wi-Fi, lowering the brightness of the screen to minimum levels, and muting the sound output.
